Air Handler Plenum Design, The air has mass inertia and as piston draws a vacuum on the valve end of the plenum runner the air starts to accelerate towards and through the valve somewhere steady state is reached. In all systems low pressure drop design can yield significant energy savings. Recirculation Air Handling System Design Schematic at Facility C The recirculation fan system shown above referred to as Facility C in a recent benchmarking study uses VFD controlled vane axial fans to pressurize a large plenum.

The plenum actually becomes a heat source as it is warmed by air from the furnace and extends the warmth as air continues through the ductwork. A Area of plenum box Square feet ft2. The pressure drops in the return. I have a square plenum on my air handler.
The major parts of plenum box design may include.
The supply plenum sits directly on top of the AHfurnace or the AC coil in an upflow configuration. This reduction also improves the air flow characteristics at the branch ducts that are closest to the air-handling unitThe 50 rule is demonstrated in Figure 5 on the next pageNote that at the start of the plenum there is an available air volume of 1200 cfm and an available velocity of 900 ftmin. This design is inherently low in pressure drop. If there is more than one return coming into the air handler there will be plenums on both sides. Most commonly HVAC plenum boxes are manufactured by using galvanized steel plastics or some. In all systems low pressure drop design can yield significant energy savings.
